Remove all fields for payment form

Hi for example I want to remove all fields in ‘bank transfer’ like this:

add_filter( "adverts_form_load", function($form){

    if( $form['name'] !== "adverts-bank-transfer" ) {
        return $form;
    }

    //remove 'adverts_person'
    foreach( $form["field"] as $key => $field ) {
        if( in_array($field["name"], array( "adverts_person" ) ) ) {
            unset($form["field"][$key]);
        }
    }

    //remove 'adverts_email'
    foreach( $form["field"] as $key => $field ) {
        if( in_array($field["name"], array( "adverts_email" ) ) ) {
            unset($form["field"][$key]);
        }
    }

    return $form;

} );

It remove all fields. But it seems doesnt work, nothing happens after i click ‘place order’.
